About 09WK0KZ

09WK0KZ is the ICD-10-PCS code for a revision procedure on the nasal mucosa and soft tissue using an open approach with nonautologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 09W70KZ (right tympanic membrane), 09W80KZ (left tympanic membrane), 09W90KZ (right auditory ossicle), 09WA0KZ (left auditory ossicle), 09WH0KZ (right ear) and 09WJ0KZ (left ear).

The same procedure with a different approach is coded 09WK3KZ (percutaneous), 09WK4KZ (percutaneous endoscopic), 09WK7KZ (via natural or artificial opening), 09WK8KZ (via natural or artificial opening endoscopic) and 09WKXKZ (external).

With a different device, use 09WK00Z (drainage device), 09WK07Z (autologous tissue substitute), 09WK0DZ (intraluminal device), 09WK0JZ (synthetic substitute) and 09WK0YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
